“…Recently, Nanocellulose is explored as matrix material for the fabrication of inorganic‐organic nanocomposites as it can provide synergistic properties with environmentally benign and energy efficient production routes. Nanocellulose based composites integrated with optical, electronic, magnetic and mechanical properties of inorganic nanomaterials showed broad range of applications like catalyst, energy storage, sensors, electronics, water purification, antimicrobial properties etc.…”

In this work influence of silver (Ag) nanoparticles (NPs) on cellulose nanofibers (CNF) was investigated. Free standing composite films of CNF/ polyvinylalcohol (PVA) ‐ Ag NPs have been synthesized by ex‐situ method. Composite films with different Ag NPs content (1%, 10% and 20%) were obtained and characterized by various techniques such as UV‐visible absorption spectroscopy, field emission scanning electron microscopy (FESEM), Infrared (IR) spectroscopy and Thermo gravimetric analysis (TGA). A UV‐vis absorption spectroscopy study demonstrates that as Ag NPs content increases the optical transparency decreases. The FESEM studies of the composite films revealed the presence of Ag NPs with average size ∼ 20 nm. Infrared spectroscopy illustrates that the CNF/PVA and Ag NPs are bound through electrostatic interactions. Comparison of the thermal properties of the CNF/PVA and the CNF/PVA ‐ Ag composite films showed that the thermal stability is improved for the highest Ag content composite films. It is shown that the CNF/PVA ‐ Ag composites have potential antibacterial effects against Gram‐positive bacteria (Bacillus subtilis) and Gram‐negative bacteria (Escherichia coli).

“…Sepiolite has been also cross‐linked to cellulose nanofibers (CNF) using ultrasonication to produce very stable viscous gels from which it is possible to produce films that can be considered as “hybrid nanopapers” ,. Actually, combination of CNF to diverse type of inorganic nanoparticulated solids, such as Ag, Ni, Fe 3 O 4 , TiO 2 , carbon nanotubes or graphene, is an attractive topic of research addressed to the preparation of new systems for applications in catalysis, environmental remediation, sensors and biosensors, etc . In these works, it is claimed that the selected NP are directly assembled to the cellulose nanofibers through various synthetic approaches.…”

This account discusses on diverse general approaches employed for the preparation of heterostructured materials based on the immobilization of metal oxides and other nanoparticles on sepiolite and palygorskite fibrous clay minerals, showing the many opportunities of application offered by the resulting materials. Various examples from our own experience have been selected to show how sepiolite acts as a convenient nanoplatform for immobilization of diverse type of nanoparticles, such as TiO , Fe O , Prussian blue, zeolites, layered double hydroxides, carbon nanotubes and graphenes, etc., to produce functional materials for applications in catalysis, environmental remediation, sensing devices, energy production, and others.

“…Excellent alternative material of activated carbon should be available, inexpensive and chemically regenerable with efficient quantitative recovery. I this perspective, various green adsorbents materials were investigated (Kyzas andKostoglou 2014, Mahfoudhi andBoufi 2017). These new materials included natural materials, agricultural by-products and industrial wastes (Ali and Gupta 2006, Bhatnagar and Sillanpaa 2010, Sharma et al , Abdolalia et al 2014.…”

Cactus is cultivated in many regions over the world. Because of its chemical composition and its valuable nutritional and biological characteristics, cactus finds applications in different sectors such as the pharmaceutical and the food industries. Interestingly, cactus materials (cladodes, fruit seeds, peel, etc) have been explored for their probable use as adsorbents for the removal of toxic heavy metals and dyes from wastewater. Various preparations methods were used to produce cactus material-based biosorbents. These biosrbents have been investigated and successfully used for the elimination of both heavy metal and dyes from aqueous solutions. Related results showed very promising pollutant removal efficiency associated with an interesting adsorption capacity similar to other materials from various origins. This paper explores various cactus biosorbents preparations. Furthermore, their efficiency in depollution and factors controlling the adsorption capacity will be discussed.
